Hi, This is a continuation of a crash report by Igor (but I couldn't find the thread to reply properly, he). I tried running Pharo 1.2 tests using a cocoa cog compiled by my self (near 5.8b12 version, but with minor bugfixes), and the VM crashes with the info I'm pasting below. The crash occurs while executing TraitCompositionTest, which runs fine if it's run individually. btw... Pharo 1.1.1 tests runs correctly (some failures, some errors, but no crash :) )
best, Esteban

SmallInteger 0xc01 priority Program received signal EXC_BAD_ACCESS, Could not access memory. Reason: KERN_PROTECTION_FAILURE at address: 0x00000c0d printProcessStack (aProcess=3073) at /Users/MAC/Desktop/Dev/VM/cog-osx/platforms/iOS/vm/../../../src/vm/gcc3x-cointerp.c:37340 37340 printNum(quickFetchIntegerofObject(PriorityIndex, aProcess)); The program being debugged was signaled while in a function called from GDB. GDB remains in the frame where the signal was received. To change this behavior use "set unwindonsignal on" Evaluation of the expression containing the function (printAllStacks) will be abandoned.
Ok, what I can see is a longAt: that crashed. Happened to me several times with Cog when using objects as methods.
Then, you did a *printAllStacks() *which caused another crash (I think). It seems it was in the line:
self print: ' priority '; printNum: (self quickFetchInteger: PriorityIndex ofObject: proc); cr.
of #printAllStacks
if you see, the 'priority' is written, so the crash is in printNum: (self quickFetchInteger: PriorityIndex ofObject: proc);
It seems this failed because there was a SmallInteger instead of a Procces ? mmm wierd.
anyway, the real crash is in longAt: I bet that the number you are sending is negative. I would compiled the VM in development and "run and debug". Then, when it fails, open the XCode debugger and check the value sent to longAt: and its stracktrace.
cheers

Hi Esteban. When I run a big code with Cog (replace ALL unused compiled methods but proxies), I have the same error. At least the same 3 first lines:
*(gdb) **bt* #0 0x0008f18c in longAt [inlined] () at /Users/MAC/Desktop/Dev/VM/cog-osx/platforms/Cross/vm/sqMemoryAccess.h:41314 #1 0x0008f18c in longAtPointer [inlined] () at /Users/MAC/Desktop/Dev/VM/cog-osx/platforms/Cross/vm/sqMemoryAccess.h:41314 #2 0x0008f18c in mapPointersInObjectsFromto (memStart=544259160, memEnd=547015536) at /Users/MAC/Desktop/Dev/VM/cog-osx/platforms/iOS/vm/../../../src/vm/gcc3x-cointerp.c:19156
In my case, the error is that the oop to is trying to access in longAt: is negative. If you continue in the stack, in my case, is while doing an incremental GC. Hopefully we are talking about the same error.
cheers

Hi, This is a continuation of a crash report by Igor (but I couldn't find the thread to reply properly, he). I tried running Pharo 1.2 tests using a cocoa cog compiled by my self (near 5.8b12 version, but with minor bugfixes), and the VM crashes with the info I'm pasting below. The crash occurs while executing TraitCompositionTest, which runs fine if it's run individually. btw... Pharo 1.1.1 tests runs correctly (some failures, some errors, but no crash :) )
best, Esteban

Hi Esteban. When I run a big code with Cog (replace ALL unused compiled methods but proxies), I have the same error. At least the same 3 first lines:
(gdb) bt #0 0x0008f18c in longAt [inlined] () at /Users/MAC/Desktop/Dev/VM/cog-osx/platforms/Cross/vm/sqMemoryAccess.h:41314 #1 0x0008f18c in longAtPointer [inlined] () at /Users/MAC/Desktop/Dev/VM/cog-osx/platforms/Cross/vm/sqMemoryAccess.h:41314 #2 0x0008f18c in mapPointersInObjectsFromto (memStart=544259160, memEnd=547015536) at /Users/MAC/Desktop/Dev/VM/cog-osx/platforms/iOS/vm/../../../src/vm/gcc3x-cointerp.c:19156
In my case, the error is that the oop to is trying to access in longAt: is negative. If you continue in the stack, in my case, is while doing an incremental GC. Hopefully we are talking about the same error.
cheers

Hi, This is a continuation of a crash report by Igor (but I couldn't find the thread to reply properly, he). I tried running Pharo 1.2 tests using a cocoa cog compiled by my self (near 5.8b12 version, but with minor bugfixes), and the VM crashes with the info I'm pasting below. The crash occurs while executing TraitCompositionTest, which runs fine if it's run individually. btw... Pharo 1.1.1 tests runs correctly (some failures, some errors, but no crash :) )
best, Esteban

SmallInteger 0xc01 priority Program received signal EXC_BAD_ACCESS, Could not access memory. Reason: KERN_PROTECTION_FAILURE at address: 0x00000c0d printProcessStack (aProcess=3073) at /Users/MAC/Desktop/Dev/VM/cog-osx/platforms/iOS/vm/../../../src/vm/gcc3x-cointerp.c:37340 37340 printNum(quickFetchIntegerofObject(PriorityIndex, aProcess)); The program being debugged was signaled while in a function called from GDB. GDB remains in the frame where the signal was received. To change this behavior use "set unwindonsignal on" Evaluation of the expression containing the function (printAllStacks) will be abandoned.

Hi Esteban. When I run a big code with Cog (replace ALL unused compiled methods but proxies), I have the same error. At least the same 3 first lines:
(gdb) bt #0 0x0008f18c in longAt [inlined] () at /Users/MAC/Desktop/Dev/VM/cog-osx/platforms/Cross/vm/sqMemoryAccess.h:41314 #1 0x0008f18c in longAtPointer [inlined] () at /Users/MAC/Desktop/Dev/VM/cog-osx/platforms/Cross/vm/sqMemoryAccess.h:41314 #2 0x0008f18c in mapPointersInObjectsFromto (memStart=544259160, memEnd=547015536) at /Users/MAC/Desktop/Dev/VM/cog-osx/platforms/iOS/vm/../../../src/vm/gcc3x-cointerp.c:19156 In my case, the error is that the oop to is trying to access in longAt: is negative. If you continue in the stack, in my case, is while doing an incremental GC. Hopefully we are talking about the same error.
probably yes, because #becomeForward: also using same routines as in GC for traversing object memory graph and rewriting old object location(s) with new ones i,.e. mapPointersInObjectsFromto().
[here i get rid of overquoting]

This means that somehow one of the scheduled processes are become small integer and printAllStacks fails to print its priority and causes one more protection failure :)
So, i recommend: - add the safety measure in printAllStacks() to check if process is really an instance , not smallint. - find why one of the processes become integer :)
Esteban, could you make progress with this? is it still happening with latest available Cog ?

here is a little patch which should help with that
